Installing No-Cut Electric Strikes

Some manufacturers advertise that no frame or strike box cutting is required in standard ANSI prep doorjambs. Other manufacturers indicate there is no modification to the face of the doorjamb. Not every doorjamb is standard.


Important: When installing a “No Cut” electric strike, make certain the deadlatch is in the correct position for smooth operation. If the door does not close and latch easily and smoothly, under the power of a properly adjusted door closer, make whatever repairs and adjustments necessary prior to the installation of the electric strike to insure smooth operation.

Because the alignment is important for a “No Cut” electric strike, some manufacturers offer vertical and horizontal faceplate adjustment. Many “No Cut” electric strikes have a vertically adjustable “ramp.” The “ramp” can have a cutout through which the deadlatch slides. The adjustable “ramp” determines the position of the latchbolt that can be accommodated. The deadlatch passes through the cutout in the ramp when the door is opened and closed. The deadlatch must not contact the ramp when the door is opened or closed.

The horizontal adjustment is used to position the deadlatch directly above the keeper to ensure the lock remains locked until the keeper is retracted.

When the keeper is released, the deadlatch extends into the electric strike pocket. To push the deadlatch and the latchbolt simultaneously into the latch body, the “No Cut” Electric Strike utilizes an internal ramp. The latch is compressed to an open position by the ramp. Opening the door provides a similar operation to rotating the lock’s knob or lever.

“No Cut” electric strikes are available in different configurations including 12 and/or 24VDC, Fail Safe and/or Fail Secure and ANSI/BHMA A156.31 Grade 1, 2 or 3. Some are available Fire Rated and/or UL 1034 burglary-resistant listed. The Camden 20 Series “No Cut” electric strikes have pre load in Fail Secure models that range from 20 pounds to 65 pounds.

Before purchasing a “No Cut”, electric strike, be sure to read the printed material to determine exactly what features satisfy your customers requirements.

Important: Always discuss an electronic installation with the local authority having jurisdiction (LAHJ) prior to installing.
